ADJUSTABLE SIDING SQUARE OR HOOK.

SPECIFICATION forming part of Letters Patent No. 246,831, dated September 6, 1881.

Application filed February 10, 1881. (ModeL) To all whom it may concern Be it known that we, CHARLES W. SPIcK- ERMAN and JEREMY R. MARTIN, of Winnebago City, in the county of 'Faribault and State of Minnesota, have invented a new and Improved Siding Square or Hook, of which the following is a specification.

The object of this invention is to provide an adjustable square for marking siding-boards by for a house, in order to cut perfect joints when the house-casings or corner-boards are beveling or drawn back by nailing.

The ordinary siding-hook, as it is commonly called, consists of a narrow straightedged fiat plate having fixed at each end, on its lower face, a lug parallel and perpendicular with the plate edges and projecting three quarters of an inch, or thereabout, from the face of the plate, and the tool is used by plac- 2o ing its face or flat side upon the face of the siding-board, so that the lugs will bear against the edge of the casing or corner-board, as the case may be, so that the marking-edge of the tool will be parallel with the edge of the said casing or corner-board, and a line drawn along the edge of the tool would be the exact line where the siding-board should be cut off. The commonly-used hook, however, will not serve as a guide for accurate markings when the 0 edge of the casing or corner-board is not dressed square or is drawn back by nailing.

The invention consists in setting the lugs or posts back from the edges of the plate, and in passing through each post or lug laterally 3 5 from its outer face an adjustable gage-screw, which screws, when the tool is applied to the siding board to mark it for jointing with the corner-boards or casing of a house, are set in or out, as the case may be, against the edge of said casing or corner-board, so as to bring the edge of the tool in the desired position for marking for a perfect joint, however much the edge of said casing or corner-board may be beveled or drawn back.

Figure l is a front elevation of a portion of a house, showing the improved siding-square applied. Fig. 2 is an enlarged sectional plan view of the same, showing the manner in which the improved siding-square is applied, an end view of said square being given. Fig. 3 is a front elevation of the siding-square. Fig. 4is a side elevation of the same. Fig. 5 is an end view of the siding-square, showing its application for marking by for jointing a sidingboard with a bevel-edged corner-board or casing.

Similar letters of reference indicate corresponding parts. I

In the accompanying drawings, A represents the siding square or hook, consisting of a narrow straight-edged flat plate, a, of metal, havin g formed or attached to its upper face a bandle, I), and having fixed or formed at each end, on its lower face, two perforated lugs or posts, 0 0, that are parallel with the plate edges and. project at right angles from the face of the said plate a, said lugs c 0 being set back a half an inch, or thereabout, from the said plate edges, and those at one end being longer than those at the other to compensate for the bevel of the siding-boards. Through each post or lug c is a lateral perforation, c, and formed or fixed on the outer faces of the lug 0, about the perforation c, is an internally screw-threaded thimble or boss, (1. Through boss 01 and perforation c in each post or lug c is passed from the outside an adjustable gage-screw, B, having preferably a flat head, to serve as a gooal and sufficientbearing-surface against the edges of casings or corner-boards. These gagescrews B may be adjusted with their heads extending or projecting beyond the edges of the plate a, or with their heads against the thimbles or bosses d, or at any intermediate point.

0 represents an upright corner-timber of a house; D, the sheathing; E, the corner-boards, and F, siding-boards, which siding-boards are ordinarily about half an inch thick and six inches wide and run horizontally on the house, and have to be cut so that they will be just long enough to go in between the cover-boards or casings, as the case may be, the window and door frames being known as casings.

Nails fare driven on a horizontal line between the cornerboards E into the sheathing 5 D, so that the said nailsf shall project beyond the said corner-boards E, and a sidingboard F is then rested on these nailsf, and its ends run by the casin g or the corner-boards E. The square A is then placed on the face of the board F, with flat side down, and with the posts 0 0 extending beyond the edge of said board F, and the gage-screws B are adjusted so that their heads shall bear against the edge of the corner-board E, and so that the edge of the square A shall be parallel with and perpendicular to the said edge of the corner-board E.

If the edge of the corner-board E be truly dressed and not drawn by nailing, the screws B on that side of the square A which is in use will be set with their heads perpendicular with the side or edge of said square, so that the board F may be marked correctly with the edge of the board E along the edge of the square A. If, however, the edge of the corner-board E is beveled inward the ga ge-screws B must be adjusted with their heads extended beyond the side of the square A, in order to bring said square side in position for proper marking of the board F, while if the board E have an outward beveled edge, as shown at 9, Fig. 5, the gage screws B must be run in with their heads within or inside of the edge of the square A, so that said edge may be brought parallel with and perpendicular to the upper edge of the said corner-board E.

The gage-screws B on the opposite side of the square A may be kept adjusted for fitting the opposite ends of the sidings F, so that said square A would not require constant turning 0 about or adjustment for the opposite ends of said boards.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a siding square or hook constructed, substantially as herein shown and described, of a straight-edged plate, a, prox ided on its under face with posts 0 c and gage-screws B B, as 0 set forth.

2. The combination, with the straight-edged plate a, provided with posts 0 c, of the gagescrews B B, substantially as herein shown and described.
